bind Spring HandlerInterceptor only to one controller
提问by Martin Dürrmeier
Using Spring 3.0.2.RELEASE. I'm having 2 Controllers in package com.myCompany. The Controllers are activated via Component-scan
使用 Spring 3.0.2.RELEASE。我在 com.myCompany 包中有 2 个控制器。控制器通过组件扫描激活
<context:component-scan base-package="com.myCompany" />
then I'm having a interceptor bind to the 2 controllers via
然后我有一个拦截器绑定到 2 个控制器通过
<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
<property name="interceptors">
<list>
<ref bean="myInterceptor"/>
</list>
</property>
</bean>
How can i bind the interceptor to only one specific Controller or to only certain methods inside a Controller? Background: I want to inspect the URL that it contains certain parameters
如何将拦截器仅绑定到一个特定的控制器或仅绑定到控制器内的某些方法？背景：我想检查包含某些参数的 URL

When you inject interceptors into a HandlerMappingbean, those interceptors apply to every handler mapped by that HandlerMapping. That was fine in the pre-annotation days, since you'd just have configure multiple HandlerMappingbeans. However, with annotations, we tend to have a single DefaultAnnotationHandlerMappingthat maps everything, so this model doesn't work.
当您将拦截器注入HandlerMappingbean 时，这些拦截器适用于由该映射的每个处理程序HandlerMapping。这在预注释时代很好，因为您只需要配置多个HandlerMappingbean。但是，对于注释，我们倾向于有一个DefaultAnnotationHandlerMapping映射所有内容的单个，因此该模型不起作用。
The solution is to use <mvc:interceptors>, where you explicitly map paths to interceptor beans. See the docs, and this example:
解决方案是使用<mvc:interceptors>，您可以在其中显式地将路径映射到拦截器 bean。请参阅文档和此示例：
<mvc:interceptors>
<mvc:interceptor>
<mvc:mapping path="/secure/*"/>
<bean class="org.example.SecurityInterceptor" />
</mvc:interceptor>
</mvc:interceptors>
